Auto Browser
What it is
Auto Browser is a Chrome side-panel AI agent that reads webpages and carries out tasks described in plain English. It examines a page’s accessibility tree and can click, type, scroll, and navigate. It can also use tools that a page exposes through WebMCP rather than interacting through the DOM. Supported AI options include Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter, and local OpenAI-compatible endpoints such as Ollama and LM Studio. Users can change providers during a conversation without losing its history. The extension is free to install; Google Gemini and OpenRouter charge per request when used with the user’s API key. The maker says the extension has no backend and does not receive or store prompts, browsing activity, conversation history, or API keys. With a cloud provider, prompts and relevant page context go directly from the browser to that provider. The maker says Gemini Nano and local LLM options send no data from the device through the extension. Write actions require approval, arbitrary JavaScript prompts for approval, and banking, government, and healthcare origins are blocked by default. Basic use requires Chrome 126 or newer.
